In this case that is probably not a problem, but it
is a bad habit to get into, and not very polite.

Nope. newStdGen is specified in terms of split, which means it
leaves the random generator in a state independent of the generator
it returns. Perfectly safe. (I think you think you used getStdGen).
I was referring to randoms and randomRs.
They clobber the generator. You can then get
a new one using newStdGen, but that forces
you back into the IO monad.
Oh, of course. Or call split first.
